You’ve probably heard of “You Posted In The Wrong Neighborhood,” even if you don’t know exactly what it is. But don’t worry — we have the full breakdown here, so you’ll finally understand what’s going on the next time you see it referenced on an online message board.

By now, it’s a pop culture references that has turned into a fairly popular meme, but it actually started as a badly remixed song. The song, “You Posted In The Wrong Neighborhood” byＳＨＯＫＫ青, was released three years ago. It combines “Shake That” by Nate Dogg and Eminem with the instrumental from “Casin” by glue70 — an ultimately odd combination.

Here’s the Nate Dogg and Eminem song, in case you were wondering.

And here’s the glue70 song, which takes on a completely different tone.

They don’t necessarily seem like songs that should go together, but someone got creative and decided to Frankenstein the sh*t out of the two songs to create a musical experiment that would go down in pop culture history.

Voila! Here’s “You Posted In The Wrong Neighborhood,” in all its meme glory:

Some users even remixed the “”You Posted In The Wrong Neighborhood” with other meme-inspiring songs, such as “All Star” by Smash Mouth and “Toto” by Africa. Let’s just say that people weren’t afraid to get creative.

In fact, no one can figure out the origin of the remix video, leaving Redditors who have searched for answers completely baffled.
